“Ordered the kit, had a couple of questions about where to mount the isolator and how long the cables are. True’s support answered pretty quickly, and I got a tip that helped hide the wiring from splash damage. After using the UTV dual battery isolator for several months, it’s still solid as day one.”

Frequently Asked Questions

Why does the LED stay on after the engine is turned off?
What makes this UTV battery isolator different from standard ones?
When we talk about a True® dual battery isolator, what sets it apart from many other isolators on the market comes down to a few key features:
Smart Charging Technology – True isolators often have intelligent circuitry that ensures your auxiliary battery charges efficiently without overloading the starter battery. Many standard isolators just split voltage without optimizing charge.
High Current Capacity – True isolators are rated for heavy-duty use (often 140A+), which means they can handle multiple accessories like fridges, winches, lights, and inverters simultaneously. Many generic isolators are rated lower, limiting what you can run safely.
Durability & Build Quality – True isolators are designed for off-road and harsh conditions. They usually have solid connectors, robust casings, and corrosion-resistant terminals, unlike cheaper models that may fail under vibration or weather.
Voltage Sensing & Protection – True units often include voltage-sensitive relays or smart circuitry that prevent your starter battery from being drained, automatically disconnecting loads when necessary. Cheaper isolators may not protect your starting battery as effectively.
Compatibility & Easy Installation – True isolators are designed to fit popular vehicles (like Ford, Toyota, Honda, Jeep) with minimal modifications. Other brands might require custom wiring or extra components.
